Patent FR-2228487-A1 (FR)
IPC: C07C237/30
Filed: 1974-05-06
Abstract: Pharmacologically active m-carbamoylphenylethanolamine derivatives of the accompanying formula (I) or their pharmaceutically acceptable salts are prepared. In the formula (I): R4 and R5 denote hydrogen or lower alkyl, R6O denotes an etherified hydroxy group and R7NH denotes a substituted amino group. These compounds are prepared in particular by catalytic hydrogenation of corresponding m-carbamoyl-p-alkoxy(or subst.-alkoxy)-N,N-dibenzylglycylbenzenes in the presence of ketones or aldehydes which yield the group R7. Instead of the carbamoyl group, there can be a carbalkoxy group in the starting compounds, and in this case following the hydrogenation the carbalkoxy group is converted into the carbamoyl group by reaction with an appropriate amine or with ammonia. The compounds are selective blockers of ss1-adrenoreceptors having minimal effects on ss2-receptors of the peripheral circulation, e.g. of the lung. Owing to these effects, they can be employed for the treatment of cardiovascular diseases, e.g. angina pectoris, hypertension and cardiac arrhythmia.

Title: Machine erecting cardboard box blanks - has vertically movable carriage holding blanks and operating folding levers
IPC: B31B3/46
Filed: 1974-05-30
Abstract: The sheets of cardboard, previously cut to size and grooved, are fed individually through a slot in the side of the machine. A stop positions the sheet, which is then lifted upwards by a ram mounted in the base of the machine. The ram passes through an opening in the surface on which the sheets are delivered. As the sheet is lifted, its edges are bent through 90 deg. by convex surfaces. After the sheet leabes the convex surfaces it is held by a carriage movable vertically and reinforcing folds are made by curved levers on the carriage. These levers are rotated y rack and pin ion gears as the carriage moves upwards. Pivoting flaps hold the sheet in the carriage during its passage through the machine.

Title: Prodn. of transformer winding cooling channel - by passing section of metal strip winding between cogs to form spacing corrugations
Inventor: GARNOUX JEAN-LOUIS
IPC: H01F41/04
Filed: 1974-08-09
Abstract: The cooling channel is for transformers, particularly low voltage types, where the conductor winding is in the form of a metal ribbon (12). The winding is laid on the former in the usual manner but at predetermined intervals the band is corrugated (11) spacing the previous and later windings without the use of any further inserts. The metal band is fed to the transformer through a pair of cogs which are partially interlocked to form the corrugations at the required intervals by an automatic engaging system, the cogs being motor driven, during winding of the normal flat or plain ribbon the two cogs are withdrawn from each other.

Title: Double walled tank for wine making industry - with inner skin sepd. by spacing element from outer concrete wall
IPC: B65D90/04
Filed: 1975-04-03
Abstract: The tank has concrete walls with an inner lining and an intermediate spacing element, provided with individual, hollow projections which is fixed to the outer wall. Spaces are left between the projections and can be connected with the atmos. by the passage passing through the concrete covering the wall. In the lower part of the tank the intermediate space can be evacuated through openings; the same openings may also be used for cooling means. Other tanks may be superimposed or added at the sides, each with its own concrete walls. The spaces provide good insulation between adjoining tanks so that when one ishtd. it does not heat the contents of the next tank. The tank can be made easily and quickly and is very robust. The double wall prevents the heat of the contents from being transmitted to the external wall and vice versa.
Patent FR-2315087-A1 (FR)
Title: Parking brake pressure monitoring device - is fitted inside master brake cylinder to warn if pressure insufficient for hold-off
IPC: G01L5/00
Filed: 1975-06-18
Abstract: The master operating cylinder is fitted with a sensor which monitors the brake pressure by the effect on the sealing gaskets of the cylinder. The monitor operates electric contacts when a set pressure is reached, which corresponds to a set brake pressue. This pressure level is chosen as the minimum level required to operate the hold-off brake cylinders. The hold-off cylinders are usually locked in the 'off' position and are released for parking control. The electric contacts operate a control light so that the driver can easily see if there is sufficient pressure to operate the parking brake safely.

Title: Walls of atmospheric air-blast cooler for cooling corrosive liquids - protected from corrosion by fibre glass curtains hung internally from the roof
IPC: F28C3/06
Filed: 1975-09-29
Abstract: Reinforced fibre glass curtains coated with PVC and suspended internally from the roof of atmospheric coolers by S-shaped hooks or cord wound round bars, protect the cooler walls from corrosive liquid containing substances liable to precipitation. The curtains are weighted at the bottom sufficiently to keep them straight, but not enough to prevent them being moved by the eddy currents of air in the cooler produced by the fan blowing in the cooling air. Each curtain covering one wall of the cooler is made up of several cloths welded together. Any droplets or encrustations landing on the curtains do not settle due to the agitation produced by the eddy currents and fall to the catchment pit in the base of the tower. Encrustation on the curtains can be removed during short stops by shaking by hand. For atmospheric cooling towers for cooling corrosive liquids, e.g. the hot electrolyte containing zinc sulphate and sulphuric acid from zinc refining. Prolongs the life of the cooling tower and allows less expensive materials of construction to be used. Curtains are cheap and easy to erect and replace.

IPC: G06F11/10
Filed: 1976-01-20
Abstract: Numerical control by key number in which each number, A, having n decimal figures (An,---Ai ---A1) is associated with a key number Q. The key number is obtained from the number A by a calculation which includes three stages. The number system has a principal input to which are successively applied all the figures Ai of the number A and the figures of the key number Q. These figure being coded in BCD. A transcoding device whose input is connected to the principal input produces from the figures An- -Ai figure A1 and from the numbers bn---bi figure b1 also binary coded. The transcoder supplies from the coded number q the number d1=p-Q1(q) modulo p, Q1 being the invene operator of Q. A pulse generator controlled by the signals obtained at the output of the transcoder, delivers for each number bi applied, a train of pulses whose number is equal to the number bi.

Title: Water-resistant semiconducting electric power cable sheath - comprising polymer contg. silane incorporated after addn. of carbon black
Inventor: PRIGENT MADELEINE
IPC: C08K9/06
Filed: 1976-05-25
Abstract: An electric power cable which is resistant to humidity comprises: a conducting core; a polymeric insulating layer; and a semi-conducting sheath. The latter is made from a high polymer, filled with carbon black, pref. 10-40 wt.% and contains 0.05-4, pref. 0.1-2, wt.% of a silane. The resistivity of the semi-conducting sheath is pref. 100 ohm cm. The silane may be vinyl-tris(2-methoxyethoxy)silane, mercaptopropyltrimethoxysilane, or N-beta (aminoethyl) gamma aminopropyltrimethoxysilane. It is pref. incorporated in polyethylene or ethylene-propylene-diene-monomer elastomer, and is mixed in with polymer particles after the incorporation of carbon black and before they are extruded. Such cables are used underground to carry considerable power, e.g. 10 MVA. Incorporation of silane prevents progressive migration of water to the insulating layer. Its addn. after incorporation of carbon black prevents the electrical resistance of the semiconductor from rising appreciably. The silane also prevents penetration of water during cable fabrication, as when crosslinking is effected in the presence of water vapour.

IPC: E04C2/04
Filed: 1976-09-02
Abstract: Method of making lightweight building elements composed of cement and expanded polystyrene beads involves coating the beads with a homopolymer or copolymer; without using any hardener, or outside coating of cement before transporting them to the work site.

Also, the resistance to compression is increased, and a homogeneous distribution of heads in the cement is obtd.
